@ZZ when@ it may concern:

vBe it known that i, XYiLnnLn i'onnnn, of the city, county, and State ofreiv York, have invented certain non and usel'ul improvements inUprignt-iano Cases, of which the follow ing is a specification.

This invention relates to an upright-piano case that is so constructedthat the front of the case, with the key-board, can be detached quicklyand with great facility frein the rear part oi" lli-e case whenever itis required in moving the piano in or ont of houses with narrowstair-cases; and the invention consists oi' a case for upright pianos,in which the de tachable iront section, containing the key# board andthe actions, is connected to the rear section at the abutting edges bysuitable devices and by auxiliary locking devices at the lower parts ofthe sections, as will be fully deseri` ed hereinafter.

ln the accompanying dranf'ings, Figure l represents a 1perspectivevie-vvY of iny improved upright-piano case. Fig. 2 is a side elevationoi" the same, draivn on larger scale. Fig. 3 is a side elevation of thedetachable frontsection; lfig. d, an end vier.v oil the abutting edgeol" the rear section oi' the ease, and Fig. 5 isa horizontal section online it, Fig. 2..

Similar letters of reference indicate corresponding parts.

A in the drawings represents a case for npright pianos, which is n ad oftwo sections, a rear section, A', and a detachable front section, fri,which latter also supports the keyboard and the actions. The lirontedges ofr the rear part, rif, are provided with recesses a, covered b vace-plates I), havingslois b, with enlarged upper ends, which areengaged by the enlarged heads of studs b, which are attaehed to tne rearedges ol" the front section, A2, so as tolock the front section rigidlyto the slotted plates of the rear section by passing the enlarged headsb2 into the enlarged openings ol' the slotted plates l, and then guidethe shanks oi the studs lf into the contracted parts ci the slots b bylowering the front section, ln place et' the studs Zr' and slottedplates l), an;7 other fastening devices may be used by which thedetachable iront section, A1", inay be attached to the rear part, AJ, asI do not conline inyselr" to the special construe tion shown The rearand front sections, A A2, are further connected by auxiliary `asteningdevices, which are arranged at the lower parts of said sections, andwhich consist of perforated blocks or cheeks d at the lower part of therear section, A", and detachable blocks or cheeks d at the lower iartoi' the front section, A2, the latter iitting over the blocks d of therear section, and being connected thereto by bolts di, that are passedthrough holes of the blocks d d, and then sereived l'ast to the saine,as shoivn in Fig. 2. rEhe iront section, A, may be bolted to ears ol"the iron stringtraine, instead of being connected to the rear part, A,or attached in any other inanner rigidly tothe piano, so as not to bedisplaced when taking hold of the case in inoving the piano.

lhenever it is necessariT to detach the front section, A, the loiverfront panel of the case is detached and the eonneetingfooltsdZ removedfrom the blocks d d, upon which the front section, di, and the key-boardcan be readil;r disconnected frein the rear section, A', by detachingthe locking devices of their abutting edges. The connection of the irontand rear sections, A A2, is covered by projecting nioldings c of theside boards ol' the rear section, as shown in Fig. 5. To reaiitach thesections the front section is lirst connected to the rear section by thefastening devices of the abutting edges, and the sections then connectedby inserting and lastenin g the connectingbolts to the blocks d d'.

2y construct-ing the cases of upright pianos in two detachable sections,ot' `which the front section contains the keyboard and actions,

upright pianos can be inore conveniently inoved in or out of houses withnarrow staircases, as the iront section can be conveniently detached andreattached Without requiring specially-skilled hands for putting thesections together, which is the ease in upright pianos in which thekey-board is detachable i'roin the niain case, but in which the actionsare not removed with the keyboard.
